AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Sorry,I had forget one thing. From some message I knew that normalizing the data before deconvolve might underestimate the percent change of signal in some cases, then if I wanted to normalize my data after deconvolution ,How should I do? I felt sorry for my poor mathematical experience!Alhough you had explained this some time before(100*y(t)/a0 = 100 + (100*a1/m)*t + (100*b/m) * s(t) + e1(t), p1 = 100*b/a0; 100*y(t)/m = 100*a0/m + (100*a1/m)*t + (100*b/m) * s(t) + e2(t),p2 = 100*b/m = 100*b/a0 * a0/m = a0/m * p1), but I could not figure out the resolution in AFNI way. Thank you very much!
